HENRY e." voIeHT, or NEW BRITAIN, CONNECTICUT, AssIGNoR To RUSSELL a ERW'IN.

MANUFACTURING COMPANY, OF NEW BRITAIN, CONNECTICUT, A CORPORATION OF CONNECTICUT.

To allfwhom it may concern:

Be it known that I, HENRY G. VoIGHT, a citizen of' the United States, residing at New Britain, county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Panic-Bolts for Outside Doors, of which the following is a full, clear, and exact description.

My invention relates to improvements in locks and particularly to an improvement in that type shown in my accom anying application, Serial No. 475,754, 'led February 3rd, 1909, and also contains features of improvement' set forth in my co-pending applications, Serial No. 441,362,1iled July 1, 1908, and Serial No. 480,297, filed February 27, I 909.

The main object of the present invention is to provide meanswhereby the lock, may always be operated from the inner side ofthe door bymeans substantially similar to that set .forth in my aforesaid application; the' lock construction being also such that when the door is closed, the exterior operating means may be dogged or blocked against operation save by the usel of a proper key.

Other advantages will be seen by the eX- perienced locksmith.

In the accompanying drawings, Figure lis an edge. elevation of a portion of a door equipped with my improved lock. Fig. 2 is a relatively enlarged view of the lock case with one side removed and showing certain other details in section. Fig. 3 is a -View on the same scale as Fig. 1, showingr certain parts in elevation and certain other' parts in section, said section being taken on the plane oflthe line X-X, Fig. 2. Fig. 4 is a sectional View of a strike-plate adapted to this lock.

1 represents a portion of a door to which my lock is applied.

2 represents the face plate having projecting therefrom a spring latch-bolt 3 and a dog actuator`4, the latter having a beveled forward end adapted to engage the strike-plate in the saine manner as a latch, save that when the door is closed, there is no perforation in the strike-plate in front of the actuator 4. Thus, so long; as the door is closed said actuator 4 will be repressed.

represents sueha strike-plate as I have described.

G is the lor-k ense containing the latch mechanism.

PANIC-BOLT FOR OUTSIDE DOORS.

Patented May- 4, 190e.

'7 is theI inner end of a cylinder loci;L carried by the case 6, the outer end of said lock being shown at 7 a, Fig. 1.1

The tail of the latch 3 isiconstructed in the I usual manner and is adapted'to .be retracted by three independent means, to wit, a hand operated device 9, at the inner side of the door; a hand operating device 10 and the ey operated device 7 at the outer side of the oor.

l1 is a lever pivoted at 12. 13 is another lever pivoted at 12 and resting under .a shoulder of the lever'll, as best seen viii-Figs. 2 and 3.

14 is a block resting under the lever 13 and suitably uided in the case 6.

v 15 is alock cut away at 15a and mounted under the lever 11, the cut away portion 15av clearing the lever 13.

l()a is the inner end of the operating device 10, lwhich is pivot'ed on the escutcheon plate 16.

9at is a lever pivoted on the escutcheon 17, the inner end of said lever standing under the block 15, the lever being operated by the hand operated device 9 when the latter is moved in either direction toward or from the door. The operating device 9 is pivoted at 9b to the escutcheon 17 and is provided with two hooks orhorns 9c 9d which engage theV lever 9a at opposite ends and o n opposite sides sothat no matter which way the operating device 9 is moved, it will cause a movement of the lever 9l in a direction to lil't the block 15 and tilt the lever 1] so that it in turn will engage the tail ol" the b'olt 3 and retract thcsame.

18 is a spring for holding' the lever 9 in its inactive position.

3a is a spring for normally advancing the latch bolt 3.

20 isa lever pivoted at 21 in the case 6, one end of the lever engaging the tail of the latch bolt 3 so that when said lever 20 is swung back said latch bolt will be retracted.

The lever 20 is moved b v/the roll-hack of the I the three means 7, 9 or 10.

Together. with, this mechanism l provide `sto i-work whereby4 the latch bolt may be loc ed positively against retraction by the means l() and Inlay be also llocked against repression by the use oll a thin tool inserted between the edge 'of the door and the door Y casing. This means also includes a device yfor preventing the shifting of the stop-work by a thin tool inserted through this space,`

' one button is pushed in, the other will be projected and vice-versa.. The inner end of the button 23 carries a shoulder 25, which,when this button is pushed in, stands over the forward end of the lever 13 whereby it follows that said lever 13 cannot be lifted, and hence the latch 3 cannot be retracted at such time by the end 10l1 and operating device 10.

Wvhen the button 23 is pushed in, the button 22 will be projected and when the door is closed a tilting dog 26 pivoted at 27 drops by gravity to a position m' which a shoulder thereon 26 stands to the rear of .a stop or shoulder 22 on the tail of button 22 to prevent its repression.

So 'long as the door is'open, the dog 26 will stand in they osition indicated in Fig. 2, irrespective of tile position of the buttons 22H23. This is due to the fact that the dog actuator 4 stands projected. This dog "actuator 4 is connected at its rear to a swinging lever 28 pivoted at 2Q. This lever 28 carriesva stud 28a, which studprojects into a recess within the (logging plate 26, asbest seen in Fig. 2. The upper wall of this recess is inclined or so sha ed that when the actuator 4 is pushed bac the stud 28"L will move back in said recess so as to allow the dog 26 to drop down into the position previously described.

l/Vhen the door is closed and the stop-work has been set, the dog 26 also serves to block the latch bolt 3. Under such conditions, it is clear that means must beprovided to still permit the door to be opened from the outside, T o that end, I provide first a shoulder 20a on the side of the lever 20. "This shoulder stands above a notch 26h in the rear upper edge-of the dog 26. lWhen the dog is 1n the position indicated in Fig. 2, the shoulder 20 does not project into said notch 26, but,

when the dog 26 is shifted to its clogging posie tion it will be seen that the rear end of said dog will tilt up so that the shoulder 2Oa will stand in said notch.

at thai-ear oi' the recess 26b thus lifting the forward end of the dog to the position indi- Now, when the roll` back of lock `7 is turned so as to rock lever 20, Y the shoulder 20a will ride down the incline cated in Fig. 2,l first freeing the latch 3, after which, the continued rearward swinging movement of lever 20 will retract said latch bolt 3.

A suitable recessor clearance should be provided in the lock case 6 to permitthe operating levers 9a and 10a to partake of the necessary movement whereby the blocks 14-15 may be shifted.

l have only attempted to show the invention in one ofv its preferred forms and have even then not attempted to show the precise design that might be adopted in forming the working parts, the drawings being illustra tive rather than definitive in this respect.

sired, for example, thev spring 28h. may be `employed to'advance the actuator/l through Y'the medium of the lever 28 and a friction spring 22 b.51nay, be employed to frictionally hold the'stopw rkY in either of its two positions. l f

tures of imprvement Aover `the invention made the subject matter of the aforesaid applicatiomit will also be seen to contain certain other features of improvement relative to other' details.
